Book Description
This book is intended for readers who are either already familiar with celestial navigation or are planning to take up the subject, and want to learn about optional resources. This booklet does not teach celestial navigation, nor is it a copy of the Air Almanac. There are marine navigators who prefer the Air Almanac over the Nautical Almanac. This booklet compares the two almanacs so others can make their choice as well. The Sky Diagrams of the Air Almanac are an important resource for all navigators, but they can easily be overlooked by those who rely on the Nautical Almanac alone. With that in mind, we give these diagrams here a well deserved review and comparison with competing manual methods of predicting the best bodies to use for a round of sextant sights with an eye toward optimizing the accuracy of the resulting position fix. The right choice of bodies is crucial to the final accuracy. For an introduction to or review of celestial navigation, see Celestial Navigation: A Complete Home Study Course.

Languages : en
Pages : 264

Book Description
For over 150 years the United States Nautical Almanac Office has published The Nautical Almanac, first as part of the American Ephemeris and Nautical Almanac, and then on its own, to provide the US Navy with a convenient form of the astronomical data used for celestial navigation. This book is still the standard resource for marine celestial navigation for the U.S. Navy. The book is produced in collaboration with Her Majesty's Nautical Almanac Office, part of the U.K. Hydrographic Office. That Office maintains the copyright on the material it produces. The Nautical Almanac contains the following data tabulated at hourly intervals to a precision of 0.1 arcminute: the Greenwich hour angle and declination of the Sun, Moon, and navigational planets; the Greenwich hour angle of Aries; positions of the navigational stars; rise and set times of the Sun and Moon for a range of latitudes; and other data. Each edition also contains a sight reduction table; sight reduction formulas; and various correction tables for sight reduction. There is a useful concise sight reduction form at the back of the book. The Nautical Almanac is available several months in advance of its edition date.
